culty by providing a variable speed transmission for connecting the exciting genera- :or to the shaft of the main generator and a method of operating the system, whereby i operator is in complete control of the speed at which the exciting generator is driven and hence iscnabled to cause the same "so run at such a speed while the main. generator is being slurred that the field snagre quickly saturated. Under these coninain generator will pick up l'ZlPiiiiS/ and wiil deliver a. maximum uarrtitv of cor 'ent in the shortest possible time.

invention further relates to an arrangement of the exciting generator and Mansniission whereby the said generator may he used as a motor to start the apparams when for example, the main shaft is driven by an. internal combustion engine.

"u fiher ohjeccs of my invention will apiroin the reading of the annexed Specification and by reference to the drawing on which the figure representsthe invention somewha'b diagrammatically,'the transmission bein shown in cross-section.

Referring so the drawing, 1 indicates the main generator which is provided with a main shaft 2% connected to a suitable source of power, prefera ly an internal combustion engine (not shown). Tome opposite end or she shaft 2 hub 3 is keyed having a flange integral therewith which is provided on its outer face with a friction sure face 5. Suitably mounted adjacent to the fricsion surface 5 is a shaft 6 on which is mounted a hub 7 carrying. a friction disk 8, said hub being keyed to the shaft in such a manner '61 it it may slide upon the same. An arm 9 is attached to the hub and a bellcranx lever 10 having a handle 11 is mounted adjacent thereto and connected to said arm, and may he used to slide the hub 7 and friccarries also a ciutch 12 which is adapted to engage the chitch member 13 which is loosely mountedon the shaft 6 and has a bevel pinion lei formed integral therewith. The bevel. pinion is adapted to engage a hevei 15 formed upon the flange 3: when the hub T is moved by means of the heli- Viz iever 10 iLhe position shown in doi- 'nes on the drawing.

in. exciting generator 16 is directly connected to ahe shaft 6. Thisexciting generator is of the type which may be used at 6. In an apparatus of the characten described, the combination of a main generator, an auxiliary exciting. generator, a shaft for the main generator, an internal combustion engine connected to said shaft, and means operable at will for transmitting power at variable speeds from the main generator shaft to said auxiliary generator without affecting thespeed of said main-generator, comprising a.friction disk mounted on said shaft, a second friction disk slidably mounted in engagement therewith, and means for-transmitting power from said second friction disk to the auxiliary generator..

7. In an apparatus of the character described, the combination of a main genera tor, a shaft connected thereto, a dynamo adapted to operate as a motor or generator arrangedm operative relation to said shaft, means forconnecting said main generator and dynamo, whereby the latter may be alternatively operated as a motor to drive the shaft or as a generator to furnish current to the energizing coils of the main generator, and means controllable at will for r-egulatinglthe speed of said dynamo when the latter is used to furnish current to the energizing coils of the main generator.

8. In aniapparatus of the character described, the combination of. a main genera 'tor, a'dynamo adapted to operate as a motor or generator, a shaft connected thereto, a flanged member, having a friction surface and carrying abevel gear, mounted on-said shaft, a shaft mounted adjacent said flanged member and connected to said dynamo, a friction disk slidably mounted on said lastmentioned shaft and'provided with a clutch ERNEST HQ MERCHANT, i M; A. .KIDDIE.
